There are 2 options related to this but no combination allows a true choice:
- In Browser > File List > Custom filter: option "Show in preview" should apply only for the Browser Preview Pane (to allow playing or not). Current (wrong) behavior is that it also acts as a filter to includes/excludes video files from View and Full screen modes

- In View > View, the option "Autoplay (video)" allows automatic or manual start of video*. This option should only impact View and Full Screen modes. The current (wrong) behavior is that it's taken account as well as for the Browser Preview pane, triggering unwanted reading** while we are just browsing through files

Why is it painful? Once a video was played in preview pane, it's impossible to change anything with the file (move, delete, change date...). XnView locks the file and the only way is to close XnView


Also,in View mode and quick slideshow, video are always skipped, whatever the options. The only way is to go to full screen / slideshow straight from Browser.
